thank you very much for giving the names of Henry Exavier Longtin brother and sisters.
I think by reading your 1st message and looking at my files, I may have found a plausible answer to your request.
Here is what I have found in my list of unlinkables...
For the parents of Henry Exavier Longtin, I have his father Joseph Longtin born 1847 in the province of Quebec or Ontario, his mother Mary Ann (no surname) born in Illinois on 19 May 1847 and deceased on 1 Oct 1920 in Texas.
They were probably married in Illinois because their daughter Louise Longtin was born in 1873 in Illinois, their next daughter Margaret Longtin born in Illinois or Texas, their son Louis Longtin born in 1878 in Precinct #5, in Leon or DeLeon, Texas, and then their second son Henry Exavier Longtin born on Dec 29 1885 in Texas.Henry Exavier deceased on 4 July 1934 in Richmond, near Houston, Texas.
I have some other Longtin born in Texas but later on.I have a Julius E Longtin born in 1935, he could and I repeat, he could be a son of Nigul Bruce Longtin which you mentioned in your last post.Julius E Longtin could be living in Hunt, TX or in the vincinity.
That's all I can speculate at the moment. I still have to find the parents of Joseph Longtin, born in 1847 in Quebec or Ontario...
